Aparentemente sim e ja causou a segunda maior Extinção global da nossa historia. Chama se raios gama e são os provaveis causadores da Extinção em Massa do periodo Ordovician–Silurian:
"Scientists from the University of Kansas and NASA have suggested that the initial extinctions could have been caused by a gamma ray burst originating from an exploding star within 6,000 light years of Earth (within a nearby arm of the Milky Way Galaxy). A ten-second burst would have stripped the Earth's atmosphere of half of its ozone almost immediately, causing surface-dwelling organisms, including those responsible for planetary photosynthesis, to be exposed to high levels of ultraviolet radiation. This would have killed many species and caused a drop in temperatures.[7][8] While plausible, there is no unambiguous evidence that such a nearby gamma ray burst has ever actually occurred. One method would be to search the Moon for uneven exposure to gamma rays.
Adrian L. Melott et al estimated that gamma ray bursts from "dangerously close" supernova explosions occur two or more times every billion years, and this has been proposed as the cause of the end-Ordovician extinction"
Esta, por acaso, já conhecia!
ResponderEliminarÉ um perigo real e, talvez mesmo por isso, é que foi retratado no filme...
Como diziam os gauleses do "Astérix", é ter cuidado "para o céu não nos cair na cabeça".
Nós realmente tamos rodeados de perigos... como se já não bastassem os problemas cá em baixo, ainda vêm meteoritos e explosões cósmicas atormentar-nos a vida! fogo!
